Is QMEU enabled for Linux runners for docker buildx?

[ajhalili2006]

I would like to do docker buildx for my Docker images to ensure that Raspberry Pi and i836 users can still run our images without switching to amd64 ftom ARM-based CPUs.

But before we do that, do you enable QMEU on kernel-side of the Linux/macOS runners?

Hey Andrei,

For privileged containers Cirrus spins up a GCP VM with nested virtualization enabled but regular docker_builder doesn't have nested virtualization enabled. It's a matter of a flag being added on our side. 🤔 So the answer to your question is "no, it's not but we can easily add the support".

Right now the KVM flavored docker_builder VM only installs quemu-kvm:

Will you need any other packages?

Created #794 which should cover this use case in more generic way.
